FSHR and Infertility: The frequency of the S680S FSHR variant observed in the present study (which was similar in normal oocyte donors and infertile patients), was also lower than that reported in Colombians (~ 14%)(http://grch37.ensembl.org/), in whom the estimated African and European genetic admixture proportions are higher than in Mexicans (11% vs. 5% and 60% vs. 37%, respectively) [42], thus emphasizing on the substantial impact of the admixture with Spaniards on the c.2039A > G FSHR SNP in Latin America.
